Hello this is my first time on the blender forum so pardon me if this is the wrong place for this post. I just downloaded the blender publisher 2 hours ago and when I tryed to run it. It ran the MS-DOS and then opened up a title screen. Then after a couple seconds this closed and the program was all gray. When I would go over certain parts with the mouse they would go on but as soon as I left that section they went back off. I was woundering if there is a required limit to certain things such as 3D cards that your computer needs to run Blender. If that is not so could some one please tell me how to fix this problem I have. Thank you.
